i don't think it was well conceptualized and i don't think it has furthered chinese foreign policy or national security. >> woodruff: so what you have seen happen, campbell, is u.s. japan, south korea, continues military fights over that airspace, that airspace, was this -- what are the chance this is becomes a diplomatic standoff and escalates from that to a military standoff involving any of those players? >> what has gone on between japan and china has now gone on for over a year and this is like a case of the mumps, you know, it comes and goes. these territorial issues are nothing new in asia, but this particular cycle has been longer and more intense. i think the most likely thing is not a diplomatic crisis which then turns into a military crisis, but a lone actor, a guy on a fishing boat or a plane captain that basically exceeds what, you know, hopefully are occurrence rules of engagements and there is a collision or a crash or a local crisis which then has an intense short duration but in that particular area which will really cause a crisis in relations between china and japan
